FIG. 1 is a diagram illustrating a process of selecting one or more external devices by using a selection area according to an embodiment of the present disclosure.

Referring to FIG. 1, a portable electronic device 100 may display a selection area 120 having a predetermined shape on a touch screen 110. The selection area 120 may refer, for example, to a particular area that is set to allow one or more external devices (or IoT devices) to be selected in response to a user's touch input in spatial information displayed on the touch screen 110.

Although the selection area 120 is shown as a circular shape for convenience of illustration, the selection area 120 according to embodiments of the present disclosure may be set to have various shapes (e.g., an elliptical shape, a triangular shape, a rectangular shape, a polygonal shape, or a free shape, or the like).

The portable electronic device 100 may receive location information of a plurality of external devices from a server that manages the plurality of external devices. Then, based on the received location information, the portable electronic device 100 may set spatial information (e.g., in the form of a map) related to the location information of the plurality of external devices.

The portable electronic device 100 may display the selection area 120 in the spatial information. The portable electronic device 100 may receive a user's first touch input for the selection area 120 so as to select the location information of at least one external device from the location information of the plurality of external devices. For example, the first touch input may be, but not limited to, a multi-touch input and a pinch-to-zoom input as shown in FIG. 1.

The portable electronic device 100 may display an extended selection area 130 in response to the user's first touch input for the selection area 120. Also, the portable electronic device 100 may select the location information of one or more external devices contained in the extended selection area 130 in the spatial information.

On the other hand, the portable electronic device 100 may display a reduced selection area in response to the user's first touch input for the selection area 120. In this case as well, the portable electronic device 100 may select the location information of one or more external devices contained in the reduced selection area in the spatial information.

Namely, the portable electronic device 100 may vary the size of the selection area 120 in response to the user's first touch input and then select the location information of at least one external device contained in the size-varied selection area in the spatial information.

Additionally, in some embodiment, the portable electronic device 100 may scale down the displayed spatial information such that a selection area 140 (which is identical with the extended selection area 130) is displayed to have the same size as that of the original selection area 120.

FIG. 2 is a diagram illustrating a process of receiving a user's rotate touch input for a selection area and controlling one or more external devices of the same type at a portable electronic device having a touch screen according to an embodiment of the present disclosure.

Referring to FIGS. 1 and 2, the portable electronic device 100 may display, on a touch screen 200, control function information 210, 211 and 212 for controlling the external device(s) selected as described above in FIG. 1. For example, the control function information 210, 211 and 212 may be a temperature, a fan speed, and a mode, or the like, but is not limited thereto. The control function information 210, 211 and 212 shown in FIG. 2 is, however, an example only and may be modified variously for the convenience of the user.

The portable electronic device 100 may receive a user's second touch input for the selection area so as to control the external device(s) selected as described above in FIG. 1. For example, the user's second touch input may be, but not limited to, a rotate touch input for the selection area as shown in FIG. 2.

In response to the user's second touch input, the portable electronic device 100 may perform any one of control functions indicated by the control function information 210, 211 and 212 and also display related control status information 220 and 240 (which denote the state before the control and the state after the control, respectively).

Although the control status information 220 and 240 is displayed at the top of the selection area, this is merely an example. As apparent to those skilled in the art, a display position of the control status information 220 and 240 may be varied on the touch screen 200 according to design specifications.

For example, the control status information 220 and 240 may be a setting temperature of the selected external device(s). As illustrated, the portable electronic device 100 may, for example, change the setting temperature of the selected external device(s) (e.g., air conditioners) from 21 degrees to 18 degrees in response to the user's second touch input.

FIG. 3 is a diagram illustrating a process of receiving a user's rotate touch input for a selection area and controlling one or more external devices of different types at a portable electronic device having a touch screen according to an embodiment of the present disclosure.

While the external devices disposed in the selection area (e.g., selected external devices) in FIG. 2 have the same type, the selected external devices shown in FIG. 3 are of different types.

Referring to FIGS. 1 and 3, the portable electronic device 100 may select the location information of the external devices of different types disposed in a selection area 320 in response to the user's first input. In addition, the portable electronic device 100 may identify each external device corresponding to the selected location information and then display external device type information 310, 311, 312 and 313 about the identified external devices on a lower portion of a touch screen 300. For example, the external device type information 310 to 313 may include, but is not limited to, an air conditioner, a TV, a lighting device, and a thermometer.
